Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically to a modular slurry multilayer filtration device. Background Technology

[0002] Sludge slurry is a mixture containing a large amount of solid particles and water, produced during wastewater treatment. Filtration of sludge slurry is a crucial step in wastewater treatment because it not only affects the treatment efficiency but can also cause secondary pollution. Treatment of sludge slurry can reduce environmental pollution and enable resource recycling. For example, treated sludge can be used as fertilizer in agricultural production or as building material in the construction industry. Furthermore, the organic matter in the sludge slurry can be used to produce biogas through anaerobic fermentation for energy production.

[0003] However, most existing filtration equipment for sludge slurry is an integrated structure, which is bulky and requires a certain size of the application site, making it inconvenient to use. Moreover, the internal structure of the equipment is complex, making maintenance difficult and inconvenient. At the same time, the existing sludge slurry filtration equipment has poor filtration accuracy, which limits the reuse efficiency of sludge slurry. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a modular slurry multilayer filtration device.

[0005] The technical solution of this utility model is as follows: a modular slurry multilayer filtration device, including a base, a fixed filter box set on the upper end of the base, several movable filter boxes sequentially and movably connected to the upper end of the fixed filter box, a disassembly cover plate movably connected to the upper end of the uppermost movable filter box, and a drive motor set on the upper end of the disassembly cover plate; connecting rods are provided on both sides of the upper end of the base.

[0006] A drain pipe is installed on the outer wall of the fixed filter box;

[0007] Each movable filter box has a sliding seat on both sides that corresponds to and slides into the two connecting rods; each movable filter box has a filter screen at the bottom, and each filter screen is rotatably engaged with a toggle plate via a bushing; the aperture of each filter screen decreases from top to bottom.

[0008] The two sides of the disassembly cover plate are also equipped with sliding seats that correspond to the two connecting rods and slide and engage with each other; the top of each of the two connecting rods is threaded with a locking nut that abuts against the upper surface of the disassembly cover plate; a feed pipe is provided at the top of the disassembly cover plate.

[0009] The output end of the drive motor is equipped with a splined shaft that simultaneously slides and engages with each bushing and rotates and engages with the bottom of the fixed filter box.

[0010] Furthermore, the fixed filter box has a first slot on its upper surface and a first positioning sleeve on its lower surface; the movable filter box has a second positioning sleeve at its bottom that can be movably engaged with the first slot, and a second slot at its top that can be movably engaged with the first positioning sleeve.

[0011] Note: The movable filter box is movably engaged with the first slot on the fixed filter box via the second positioning sleeve at its bottom end, and is movably engaged with the first positioning sleeve on the disassembly cover via the second slot at its top end. This helps to improve the connection stability between the movable filter box, the fixed filter box, and the disassembly cover.

[0012] Furthermore, the filter screen is movably connected to the movable filter box via a screw;

[0013] Note: By movably connecting the filter screen to the movable filter box, it is easy to replace the filter screen, thereby reducing the maintenance cost of the device.

[0014] Furthermore, an arc-shaped baffle is movably installed on the outer arm of the movable filter box, and a sludge discharge box is installed on the outer wall of the movable filter box at a position corresponding to the arc-shaped baffle. The arc-shaped baffle is engaged with the inner wall of the sludge discharge box, and a push screw that is rotatably engaged with the outer wall of the arc-shaped baffle is rotatably engaged on the sludge discharge box. A sludge guide hopper is provided through the bottom end of the sludge discharge box.

[0015] Explanation: During the sludge filtration process, solid matter in the sludge is blocked on the filter screen. At this time, by pushing the screw to move the arc-shaped baffle inside the sludge discharge box, the solid matter on the filter screen enters the sludge discharge box under the action of the agitator and is finally discharged through the sludge guide hopper, thereby improving the operational reliability of the device.

[0016] Furthermore, the base is equipped with an extrusion assembly that is simultaneously connected to each mud guide hopper; the extrusion assembly includes an extrusion cylinder that is mounted on the base and simultaneously connected to each mud guide hopper, a compression motor mounted at the top of the extrusion cylinder, and a pressure plate that is slidably engaged inside the extrusion cylinder; a release plate is movably inserted at the connection between each mud guide hopper and the extrusion cylinder; a discharge gate is movably mounted at the lower end of the outer wall of the extrusion cylinder; the output end of the compression motor is connected to a drive screw that is threadedly connected to the pressure plate.

[0017] Explanation: Solid matter on the filter screen enters the extrusion cylinder through the corresponding sludge guide hopper. At this time, the compression motor drives the drive screw to rotate, and the pressure plate moves downward along the inner wall of the extrusion cylinder under the action of the drive screw, extruding the solid matter. The compressed solid matter is discharged through the discharge gate, which helps to improve the volume reduction treatment effect of sludge slurry.

[0018] The working principle of this utility model is as follows:

[0019] In use, the movable filter box is assembled with the fixed filter box, connecting rod, and disassembly cover plate. The slurry to be filtered is then injected into the movable filter box at the top of the base through the feed pipe. The slurry is filtered by the filter screens inside each movable filter box, and the filtered wastewater is discharged through the drain pipe. During the slurry filtration process, the drive motor drives the spline shaft to rotate, which causes the agitator to rotate on the corresponding filter screen, agitating the sludge slurry. During the sludge slurry filtration process, solid matter in the slurry is blocked on the filter screen. At this time, the screw is pushed to move the arc-shaped baffle inside the sludge discharge box, so that the solid matter on the filter screen enters the sludge discharge box under the action of the agitator and finally enters the extrusion cylinder through the sludge guide hopper. At this time, the compression motor drives the drive screw to rotate, and the pressure plate moves downward along the inner wall of the extrusion cylinder under the action of the drive screw, compressing the solid matter. The compressed solid matter is discharged through the discharge gate.

[0020] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0021] First, the present invention has a reasonable structural design and a modular design, which facilitates the replacement and maintenance of various internal components, effectively reduces the maintenance cost of the device, improves the operational stability of the device, and provides reliable equipment support for the efficient filtration of sludge slurry.

[0022] Secondly, this utility model utilizes multiple filter screens with different pore sizes to perform multi-stage filtration of sludge slurry, which effectively improves the filtration effect of sludge slurry; moreover, during the operation of the device, the sludge slurry on the filter screen is continuously stirred by the agitator, which not only improves the filtration efficiency of sludge slurry, but also solves the problem of equipment downtime caused by filter screen blockage.

[0023] Third, this utility model utilizes an extrusion assembly to compress the solid sludge filtered from the sludge slurry, thereby reducing the volume of the sludge slurry, improving the convenience of transporting the remaining sludge after filtration, and saving on the treatment cost of the sludge slurry.
